Description
A novel construction principle for bridge building was developed by Max Bögl in collaboration with SSF Ingenieure and implemented in an initial pilot project. The aim of the development was the use of segments that are prefabricated under optimal conditions and can be directly driven on due to their dense surface.
They lie on the main supporting structure without shear connection and do not participate in the longitudinal load-bearing effect. As a result, the bridge can be easily adapted or renewed by replacing the segments. This results in short construction times and high construction quality.
Special features
- Static separation of longitudinal load-bearing effect (composite precast girder) and transverse load-bearing effect (sliding road slab)
- Longitudinal beams made of airtight welded steel hollow boxes with connected concrete flanges made of concrete C 50/60
- Road slab in segmental construction made of precast segments made of concrete C 50/60
- Clamping the segments of the road slab with unbonded, internally guided tendons
- Sealing of the segment joints with shield tunnel gaskets
- Directly driven road slab without sealing, covering and coping stones
